GARBURETER.

Specification of Letters Patent.

Patented J une 11, 1907.

Application lled June 29. 1905, Serial 110.267,674.

To all whom it may concern.-

Be it-known that we, THOMAS MCCORMICK and ANAN-ms MILLER, citizens otthe United States, residingy at Mount Pleasant, in the county ofl/Vestmoreland and State of Pennsylvania, have invented a new and usefulCarbureter, of which the following is a speci- 3 fication.- i

This invention-relates to improvements in xo means for supplying chargesofinotive luid to explosion engines.

One of the principal objects is to provide a novel and excecc inglysimple structure, wherein the hydrocarbon or other fluid emr 5 ployedwill be thoroughly vaporized, only as rapidly as required by the engine,and is delivered to the engine or explosion chamber thereof inpropercondition to be exploded, theapparatus operating with a highdegree 2o of e'lliciency and economy.

Affurther and important object is to provide a carbureter fromfwhich aplurality or battery of engines can be supplied withfmotive fluid, eachengine being operable without re ard to the condition or relation of anyot er connected to the carbureter.

The referred embodiment of' the invention is i lustrated in theaccompanying drawings, wherein: t

3o Figure1 1s a vertical longitudinal sectional view through the newcarbureter. Fig. 2 is a horizontal sectional view on the-line 2--2 ofFig. 1. Fig. 3 is a crossI sectional view on the line 3 3 of Fig. 1.Fig. 4 is a top plan view of the upper perforat-e partition.

Similar .reference numerals designate correspending parts in all thefigures of the draw` ings. l i

In the embodiment illustrated, a casing is 4o employed comprising abottom 5, side walls 6, end walls 7, and a top 8. Interior upright walls9 divide thc casing into outer mixing chambers 10, and an intermediatevaporizing chamber, the latter of which has a detach- 4 5 able cover 1l,comprising a section of the top 8, that bears upon the upper edges ofthe walls 9, and is packed by a suitable gasket 12, the cover beingfastened` in place by any suitable in yins, as, for instance, bolts 13.

5o' The cai rating chamber has extending across :its per and lowerportions, partitions .te and l5, spaced apart, the upper parthe tube 19.

tition 14 being spaced from the cover 11 and forming therewith an aircoi'npartment 16. The lower partition 15 is spaced from the bottom 5,forming a vapor compartment 17, which compartment 1s in communicationwith the mixing chambers 10, by means of perforations 18, formed in theinterior walls 9, below the partition 15. A perforated tube 19,preferably rectangular in cross section, as illustrated in Figs. 2 and4, has an open lower end in communication with the vapor comartment 17,thc perforations comnnlnicatmg with the space between the partitions 14and 15. The interior of the tube is cut 0H from communication with theair chamber 16, referably by extending the upper end of saidp tube tothe cover 11 ot' the vaporizing chamber. A body ol absorbenthydrocarbon-holding material 20, is interposed between the partitions 14and 15 and surrounds This material may be anything suitable for thepurpose, such as asbestos, waste, or the like.` The upper partition isprovided in its upper side with a hydrocarbon-receiving channel 2l.,extending about the tube 19, said partition having perforations r22,located on opposite sides of the channel. The lower partition 15 is alsoprovided with perforations 23. The cover 11 has a suitable supplyopening 24, which may be closed by a plug, as 125.

The air compartment 16 of the vaporizing chamber has through its coveran air inlet opening 26, closed by an inwardly o )cning check-valve 27,which valve is normally held closed by a spring 28, one end of thespring bearing on. a yoke 29, bridging the opening, the other end of thespring bearino against a nut 30, threaded upon the stem ol the valve andadjustable to vary the resistance to the opening movement of said valve.The mixing chambers 10 are, in like manner, provided with air inletopenings 30, controlled by valves 3l, similar in all respects to thevalve of the-'air chamber. Leading from the mixing chambers are pipes32, which pipes may be connected` to separate engines, valves 33 beingpreferably located in said pipes to control the passage of the motivefluid therethrough.

y In charging the carburetor, the plug 25 is removed and the hydrocarbonor other suit TOO able liquid is poured through the same into thechannel 2l, It will be seen that said channel will be completely filledand consequently, when it overows, such overflow will take place on allsides, so that ythe fluid will be distributed equally over the body ofabsorbent material, thus obviating the danger of saturating one portionof the body prior to another portion. This `is an important feature ofthe invention. The body ot absorbent material having been thoronghlysaturated, the supply opening 24'is again closed by the plug, and thevalves 33 of the delivery pipes 32 are opened. As the engines areturned, it will be apparent that suction will take place through thepipes 32,'

i exploded is delivered from the carbureters to the engines and ismanufactured and supplied only as rapidly as the engines require,depending on the speed thereof. The richness, of the mixture can bev'varied to suit the conditions of work by altering the resistance tothe dierent inlet-controlling valves. Thus, by weakening the resistanceto` the valve 27 and strengthening the resistance against quently twoengines can be operated by the the valves 3i, the vapor supplied to theengine can -be as highly charged with hydrocarbon as desired. 'On theother hand, if the resistance against the opening of the valve 27 ismade comparatively great and the spring action on the valves 31 isweakened, the reverse will take place. The structure, moreover, isexceedingly simple and can be manutactured at comparatively small cost.Furthermore, there is no thing that is liable to become inoperative orderanged, and the device, being compact, will occupy but little room,making it useful, particularly in cramped or confined places, such asautomobiles. It will thus be seen that the carbu-- reter disclosed isnot only highly eflicient, but economical in operation, and that aplurality or battery of engines can be run from l the same without inany manner interfering. `While two mixing chambers, and conseprescntdevice, it will be evident that a greater or less number of mixingchambers, and consequently of nes, can be connected to the vaporizingchamber and the structure stili be enti l f eilicient.

il om the foregoing itis thought that the construction, operation, andmany advanatacar tages of the herein described invention will beapparent to those skilled in the art, Without i'urther description, andit will be understood that various changes 1n the size, shape,proportion, and minor details of vconstruction may be resorted towithout departing from the spirit or sacriiicing any of the advantages othe invention.
